Answer:
. What's an object in your everyday life that has a lot of Kinetic Energy? How do you know it has a lot?
"Something that has a lot of Kinetic Energy is a plane and a baseball . I know this because the baseball gets energy to it when its thrown which is giving in kinetic energy".
2.What's an object in your everyday life that has a lot of Potential Energy? How do you know it has a lot? "an object that has a lot of potential energy is Water that is behind a dam. A car that is parked at the top of a hill. A yoyo before it is released. I know this because
the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors."
The current in the wires of a circuit is 90 milliAmps. If the resistance of the circuit were doubled (with no change in voltage), then its new current would be _____ milliAmps.
Answer:
[tex]I = 45mA[/tex]
Explanation:
Given
[tex]I = 90mA[/tex] --- Current
Required
Determine the new current when resistance is doubled
Using [tex]V = IR[/tex]
Initially, we have:
[tex]V = 90mA * R[/tex]
When resistance is doubled and voltage remains unaltered, we have:
[tex]V = I* 2R[/tex]
2R represents the new resistance and I represents the new current
Equate both values of V
[tex]90mA * R = I* 2R[/tex]
Make I the subject
[tex]I = \frac{90mA * R}{2R}[/tex]
[tex]I = \frac{90mA }{2}[/tex]
[tex]I = 45mA[/tex]
The new current is 45milliAmps
